Opera mini 7.5.5
on android jelly bean

Bug :

while downloading any file via opera mini if the phone gets Locked ( pattern lock ) the download stops with error.

checked repeatedly. Errors again and again. cleared data and cache , Reinstallation too can't solve the ptoblem
while the same file keeps downloading in the stock browser even with the phone gets pattern locked.

May be opera mini is not able to wakelock the background downloading (not after the screen sleep but the hard locking phone via power button).

Is there anyone who is. experiencing the same issue? or its just me who messed up something here.

Steps to reproduce the bug:

create pattern lock in settings.
check the power button instantly locks option.

start to download any file via opera mini.
press power button.
after screen gets off , unlock the phone.
check if the download has failed ?

Anyone?
